It is not an easy task to define the requirements to software systems that support businesses by reason of the dynamic of changes in business processes. The activity of finding systems requirements has been performed empirically, without systematic methods that can fulfill business objectives. The software engineering needs methods that become the activity of finding systems requirements, in a software development process, a more systematic activity. In this article is presented a software development methodology that integrates activities proposed to business modeling and requirements definition, based on a business modeling architecture. The activities proposed become the software development more systematic and focused on the organization objectives, and can be incorporated in any methodology of development based on the UP (Unified Process).
